Topology optimization of locally resonant metamaterials for high modal effective mass

Key Points

• Increased modal effective mass enhances metamaterials, resulting in improved wave propagation characteristics.
• Experimental results show a significant increase in modal effective mass values, notably 25% above baseline metrics.
• Analysis utilizes topology optimization techniques to identify ideal configurations for locally resonant metamaterials.
• Findings suggest that optimized designs may lead to advanced applications in vibration control and sound insulation.
